Ivan Kokalovic - PeerSpot reviewer
Facilitates backend service monitoring with efficient log retrieval and API flexibility
Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline. It boosts the knowledge of sales and customer support teams by allowing them to see the backend operations without needing to read the code. Its API is flexible for visualization, and its powerful search engine efficiently handles large volumes of log data. Moreover, its stability, fast search capabilities, and compatibility with languages like ANSI SQL enhance its utility in IT infrastructure.

Efficient log management enhances activity monitoring despite VPN user issue
Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users. When a VPN user logs in, it doesn't really capture the time before this. If you're testing with existing or new device integration, then the product will be good in the market.
Kyle Vernham - PeerSpot reviewer
Built-in searches and unified data access streamline alert investigation and boosts analyst efficiency
The two features I appreciate the most in Splunk Enterprise Security are the built-in searches, which have been very easy for us to get started with right out of the box, and the fact that it accesses all of our other systems. You can access it as a pane of glass rather than having to search individually. We also have the option to compare our analysts from our service to service. Splunk Enterprise Security helps our SOC team prioritize and investigate high-fidelity alerts more effectively by providing a more in-depth look and the ability to access a lot more of our data. Instead of jumping from several segmented systems, it allows us to have everything brought together in one place. For example, you have to move from our purview to our build system and to Splunk Enterprise Security, and it enables us to streamline that process. The built-in features of Splunk Enterprise Security, which we recently procured, have given us a good starting point and demonstrated the value of the product, providing an easy way to sell it to our company. The ease of getting everything into our purview helps us, and it serves as a good start for the investigation part in one location rather than what we usually have, which is jumping from system to system to system. Splunk Enterprise Security plays a role in our company's strategy to combat insider threats and advanced persistent threats by currently being in its technical test phase. We are still rolling it out, and it should help us find any insider threats based on information that our policy states should not be present in our system. Splunk Enterprise Security's risk-based alerting (RBA) has impacted our alert volume and analyst productivity because we've got many different systems feeding into it. However, it has helped to make it easier for our analysts to go through a set of events rather than 100 alerts. RBA allows us to streamline the process and customize it for our analysts. When it comes to leveraging Splunk Enterprise Security's dashboards and visualizations to communicate security posture to executives, it's pretty straightforward for any type of information. The visualization is easy to understand, but I haven't had any direct conversations with our executives.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The ability to write custom alerts is key to information security and compliance."
"One of the most valuable features is that you are able to do a very detailed search through the log messages in the overview."
"What I like about Graylog is that it's real-time and you have access to the raw data. So, you ingest it, and you have access to every message and every data item you ingest. You can then build analytics on top of that. You can look at the raw data, and you can do some volumetric estimations, such as how big traffic you have, how many messages of data of a type you have, etc."
"Graylog is valuable because it bridges technical knowledge to non-technical teams, presenting complex backend processes in a simple timeline."
"It has data adapters and lookup tables that utilize HTTP calls to APIs."
"We run a containerized microservices environment. Being able to set up streams and search for errors and anomalies across hundreds of containers is why a log aggregation platform like Graylog is valuable to us."
"Everything stands out as valuable, including the fact that I can quantify and qualify the logs, create pipelines and process the logs in any way I like, and create charts or data maps."
"I like the correlation and the alerting."
"It is stable."
"ManageEngine EventLog Analyzer is easy to gather reports to give to management. My supervisor has access to the solution and he enjoys the graphs."
"The dashboard for administrators or assigned engineers can identify vulnerabilities, activities, infected systems, large files, or DDoS attacks."
"What I found most useful in ManageEngine EventLog Analyzer is its integration with other ManageEngine applications. It seamlessly integrates throughout the ManageEngine suite, and that's beneficial. I also like that the solution has chain management capabilities, it has a modular approach, and it's easy to reach the support team."
"The most valuable features of ManageEngine EventLog Analyzer are the number of capabilities, file integration monitoring, web server log collection, and alert configuration."
"The tool's reports show activities."
"The reporting features are noteworthy, as they provide templates that streamline the process of generating reports"
"The support system is very good."
"I find the process for customizing, developing, testing, deploying, and refining detections in Splunk Enterprise Security effective."
"The features of Splunk Enterprise Security that I have found most valuable include the risk-based score and UBA/UEBA, user behavior analytics, or user and entity behavior analytics."
"I really appreciate the all-integrated SIEM feature of Splunk Enterprise Security, which serves as a one-stop shop to get all security tasks done."
"We primarily use it to correlate logs throughout the enterprise for both searching and use in investigations."
"Being able to track impossible travel logins and things of that nature is valuable. We can track user logins from various IPs, various countries, and at various times to see if everything adds up."
"We have created a few custom use cases for Splunk that have helped us detect threats faster. For example, we set up endpoint-related data models and specialized setups for various scenarios. It's more efficient than some other products I've used."
"The most valuable feature of Splunk is the management and built-in workflows."
"We were able to create a catalog of dashboards and have a holistic view at all levels. We could understand our business much better. Real-time errors, which were buried in emails before now, surfaced up on dashboards."
 

Cons

"There should be some user groups and an auto sign-in feature.​"
"Since container orchestration systems are popular and Graylog fits the niche well, perhaps they could officially support running in docker containers on Kubernetes as a StatefulSet as a use case. That way, the declarative nature of Kubernetes config files would document their best case deployment scenario-"
"Dashboards, stream alerts and parsing could be improved."
"More complex visualizations and the ability to execute custom Elasticsearch queries would be great."
"The infrastructure cost is the main issue. I like the rest. If the infrastructure costs could be lower, it would be fantastic."
"More customization is always useful."
"The biggest problem is the collector application, as we wanted to avoid using Graylog Collector Sidecar due to its architecture."
"Elasticsearch recommendations for tuning could be better. Graylog doesn't have direct support for running the system inside of Kubernetes, so it can be challenging to fill in the gaps and set up containers in a way that is both performant and stable."
"Support could improve to make the solution better."
"The first tier of customer service and support is not great."
"I would like to see more detailed reports."
"The solution should improve on its log capturing capabilities."
"Last month, we faced an issue with a Hawaiian VPN user activity."
"Last month, we faced an issue with a Hawaiian VPN user activity. It's like a Fortinet device configured for VPN users."
"What I'd like to see as an improvement to ManageEngine EventLog Analyzer is for it to be more AI-driven. Having more automation would also make the solution better."
"There's a lot to improve in terms of connectivity. Currently, we're utilizing it across various infrastructures and environments, including others' cloud. However, connecting it to our infrastructure and integrating it with some of our SMAX solutions poses difficulties."
"I would like the ability to view logs for specific instances and not have to pull the logs for the entire Cloud environment in Splunk."
"Splunk's implementation process for managing multiple indexes can be complex, especially when dealing with a large number of components."
"The initial setup is complex, but this is necessary. We needed to take into consideration how to direct log files from thousands of machines to Splunk, and how to ingest those files."
"Adding custom visualization in Splunk has been improved over the years but can still be made better by integrating more and more JavaScript visualization sources."
"The solution could improve by giving more email details."
"The area of concern revolves around the fact that Splunk is an expensive product."
"Certain sections of the developer documentation could use some updating and clarification."
"It needs to improve the way to install third-party apps and enable installation without logging into splunk.com."
